Advance Memory Buffer (AMB) Flyer - 34408 Improve FB-DIMM Performance with IDT Advanced Memory Buffers

Advanced Memory Buffers, the next generation of FDIMM controllers, allow more DIMMS in a single system, ideal for servers, workstations, storage devices and communication applications. The unique channel structure of the IDT AMB chip alleviates buffer loading issues. The IDT AMB+ family offers unparalleled power saving over standard AMB, which translates into a dramatic improvement in overall cost and energy effi ciency.

The essential building block for next-generation, high-bandwidth applications

The fully buffered dual in-line memory module (FB-DIMM) is the next generation memory architecture to meet the growing memory requirement of servers and workstations. The IDT advanced memory buffer (AMB) chip is the essential building block located on each FB-DIMM. The IDT AMB receives commands and data from the host controller to control and write/read data to/from the DRAMs on the DIMM. Commands and write data are sent southbound from the host controller to AMBs in a daisy chain fashion and interpreted by the target AMB. Status and read data are sent northbound from AMBs to the host controller also in a daisy chain fashion, passing through non-target AMBs. This unique channel structure alleviates buffer loading issues common in registered DIMM technology, enabling designers to use a large number of DIMMs within a single system. The IDT AMB complies with the latest JEDEC specifi cation for AMB and supports DDR2-533/667/800 DRAM. It also enables serial data transfer at 3.2, 4.0 and 4.8 Gbps. The IDT AMB supports servers, workstations, storage devices and communication applications that support the next generation FB-DIMM architecture. ® ADVANCED MEMORY BUFFER (AMB) 1IDT
